Description
Legierung aus Blei, Zink und Antimon. Zusatz zum Patent 382545 In der Patentschrift 367978 ist eine Legierung beschrieben, die aus Blei, Zink und Antimon mit überwiegendem Bleigehalt besteht und sich insbesondere zur Herstellung von Lagermetallen eignet. Bei dieser Legierung sind harte Kristalle der Verbindung Zink-Antimon (Zn Sb) eingebettet in ein sehr bleireiches Eutektikum. In dem Zusatzpatent 382545 ist dargetan, daß die harten Zn Sb-Kristalle ganz oder teilweise durch Kristalle der Verbindung Zn, Sb, ersetzt werden können, ohne daß die Legierung ihre technisch wertvollen Eigenschaften verliert.Alloy of lead, zinc and antimony. Additional patent 382545 in the patent specification 367 978 an alloy is described, which consists of lead, zinc and antimony with a predominant lead content and is particularly suitable for the manufacture of bearing metals. In this alloy, hard crystals of the compound zinc-antimony (Zn Sb) are embedded in a very lead-rich eutectic. In the additional patent 382545 it is shown that the hard Zn Sb crystals can be completely or partially replaced by crystals of the compound Zn, Sb, without the alloy losing its technically valuable properties.
Es hat sich nun gezeigt, daß Dichte und Härte der genannten. Legierungen noch erhöht werden durch Hinzulegieren von Kupfer. Dies Metall, am vorteilhaftesten in kleinen Stücken, kann als handelsübliches Kupfer oder in Form einer geeigneten Kupferlegierung in der nach oben genannten Patentschriften hergestellten Blei-Zink-Antimon-Schmelze gelöst werden oder auch gleichzeitig mit dem festen Blei-Zink-Antimon-Beschickungsgut in den Schmelztiegel eingeführt «-erden.It has now been shown that the density and hardness of the above. Alloys can be increased by the addition of copper. This metal, most beneficial in small pieces, can be used as commercially available copper or in the form of a suitable one Copper alloy in the lead-zinc-antimony melt produced according to the above-mentioned patents be dissolved or simultaneously with the solid lead-zinc-antimony charge introduced into the crucible.
Schon ein Zusatz geringer Kupfermengen wirkt härtend und porenschließend und erhöht die Feinkörnigkeit der Legierungen, ohne die günstig gelegenen Gieß- und Erweichüngstemperaturen merklich zu verändern. Ein Kupferzusatz bis io Gewichtsprozent der Gesamtlegierung auf Kosten des Bleigehalts hat sich am geeignetsten erwiesen.Even adding small amounts of copper has a hardening and pore-closing effect and increases the fine grain size of the alloys, without the conveniently located casting and softening temperatures to change noticeably. A copper addition up to 10 percent by weight the total alloy at the expense of the lead content has been found to be the most suitable.
